The body is lean — a trigger line, numbered steps with concrete commands, and a compact output list — with no padding or explanation of concepts Claude already knows, matching the lean-and-efficient anchor.

It provides fully executable commands (git diff, the adr_guard.py invocations), explicit file paths, and concrete waiver fields, giving copy-paste-ready guidance rather than vague direction.

The six-step sequence is clearly ordered with a validate→fix→re-run feedback loop in step 3 and a final CI validation pass in step 6, satisfying the explicit-validation-and-feedback-loops anchor.

No bundle files exist, and the skill is a concise single file under 50 lines with well-organized sections, so it qualifies for the top score under the rubric's simple-skill guidance.

The description lists three concrete actions — "Run ADR conformance checks", "explain failures", and "identify required ADR/doc updates" — matching the anchor for multiple specific concrete actions rather than the partial coverage at level 2.

It clearly states what the skill does but provides no "Use when..." clause or equivalent trigger guidance, so the "when" is missing and completeness is capped at 2 per the rubric guidelines.

It includes relevant domain terms ("ADR conformance checks", "failures", "ADR/doc updates") but lacks the common natural variations a user would actually say (e.g., "architecture decision records", "ADR violations"), so it falls short of broad keyword coverage at level 3.

The ADR-governance niche ("ADR conformance checks", "ADR/doc updates") is specific and distinct, making it unlikely to trigger for unrelated skills, matching the clear-niche anchor at level 3.
